[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-4 This utility model provides a quantitative and precise lubrication device for electric shovels, comprising: a quantitative component 1 and a fixing component 2.

[0029] Specifically, the device includes a metering component 1 and a fixing component 2. The metering component 1 includes a fixed base plate 11, and a first fixing plate 12 is connected to the upper end of the fixed base plate 11. The first fixing plate 12 is connected to a drive motor 13, and the output end of the drive motor 13 is connected to a threaded rod 14. The threaded rod 14 is connected to a threaded sleeve 15, and the threaded sleeve 15 is connected to a pressure plate 16. The upper end of the fixed base plate 11 is connected to a container 17, and the upper end of the pressure plate 16 is connected to a limit telescopic rod 18. The fixing component 2 is located on one side of the metering component 1. The fixing component 2 includes a connecting hose 21, and one end of the connecting hose 21 is connected to a lubrication head 22. The fixing component 2 also includes a second fixing plate 23, and the second fixing plate 23 is connected to a pull rod 24. The pull rod 24 has a spring 25 on its outer side, and one end of the pull rod 24 is connected to a clamping ring 26.

[0030] In this embodiment, the metering component 1 and the fixing component 2 constitute a metering precision lubrication device for an electric shovel according to this application, which realizes the operation of metering lubrication of the electric shovel and fixing the lubrication head 22.

[0031] In this embodiment, by starting the drive motor 13, the threaded rod 14 is driven to rotate, which in turn drives the threaded sleeve 15 to move downward.

[0032] It should be noted that the threaded sleeve 15 drives the pressure plate 16 to move downward, squeezing the lubricating liquid in the container 17 and squeezing it into the connecting hose 21.

[0033] Specifically, the drive motor 13 is fixedly connected to the upper end of the first fixed plate 12, and the threaded rod 14 is threadedly connected to the threaded sleeve 15. The lower end of the threaded sleeve 15 is fixedly connected to the middle position of the upper end of the pressure plate 16. The outer side of the pressure plate 16 is tightly fitted and slides against the inner side of the container 17. The lower end of the container 17 is fixedly connected to the extension plate provided on the upper end of the fixed base plate 11. One end of the limiting telescopic rod 18 is fixedly connected to the upper end of the pressure plate 16, and the end of the limiting telescopic rod 18 away from the pressure plate 16 is fixedly connected to the first fixed plate 12. The limiting telescopic rod 18 is provided in two sets and symmetrically arranged on both sides of the threaded sleeve 15.

[0034] In a preferred embodiment, by pulling the lever 24 to separate the clamp 26 from the connecting hose 21, lubricating liquid can be applied to the electric shovel through the lubrication head 22.

[0035] In a preferred embodiment, when the threaded rod 14 drives the threaded sleeve 15 and the pressure plate 16 to move downward, it drives the limiting telescopic rod 18 to extend and retract, which is used to limit the threaded sleeve 15 and the pressure plate 16.

[0036] Specifically, the end of the connecting hose 21 away from the lubrication head 22 is fixedly connected to the lower middle position of the container 17, and the second fixing plate 23 is fixedly connected to the upper end of the fixing base plate 11. The outer side of the connecting hose 21 is attached to the inner side of the clamping ring 26. At the same time, the clamping ring 26 is provided in two sets and symmetrically arranged. The pull rod 24 is slidably connected to the second fixing plate 23, and the spring 25 is sleeved on the outer side of the second fixing plate 23. One end of the spring 25 is fixedly connected to the clamping ring 26, and the other end of the spring 25 is fixedly connected to the second fixing plate 23.

[0037] In a preferred embodiment, after the lubrication head 22 has finished working, the connecting hose 21 is placed between the two sets of clamps 26, and the spring force of the spring 25 drives the two sets of clamps 26 to fix the connecting hose 21.

[0038] During use, the drive motor 13 is started first. The output end of the drive motor 13 drives the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the threaded sleeve 15, the rotation of the threaded rod 14 will cause the threaded sleeve 15 to move downward along the thread. The lower end of the threaded sleeve 15 is fixedly connected to the middle position of the upper end of the pressure plate 16. Therefore, the downward movement of the threaded sleeve 15 drives the pressure plate 16 to move downward. The outer side of the pressure plate 16 is tightly fitted and slides against the inner side of the container 17. When the pressure plate 16 moves downward, it will squeeze the lubricating liquid in the container 17 and squeeze it into the lubrication head 22 through the connecting hose 21, thereby realizing the quantitative lubrication of the electric shovel. When the electric shovel needs to be lubricated, the pull rod 24 is pulled to separate the clamping ring 26 from the connecting hose 21. The lubrication head 22 can then perform the operation of applying lubricating liquid to the electric shovel. After the lubrication work is completed, the connecting hose 21 is placed between the two sets of clamping rings 26. The elastic force of the spring 25 drives the two sets of clamping rings 26 to fix the connecting hose 21.

[0039] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
